Frequently asked questions
Short, factual answers about the Varm Silent Pool Series.
Which pools suit the Varm Silent Pool Series?
The Varm Silent Pool Series covers advised pool volumes from 25~50 m³ on the smallest model up to 70~130 m³ on the largest. It operates across -7~43 °C ambient air temperature, heating pool water up to 40 °C and cooling it in summer.
How efficient is it?
The specification table lists COP values of 4.8~7.4 across the models — at the favourable end that means over seven units of pool heat per unit of electricity. The DC-inverter compressor modulates output instead of stopping and starting, which is where the high seasonal efficiency comes from.
Is it safe for chlorinated pool water?
Yes — heat transfer happens in a spiral titanium tube inside a PVC shell. Titanium resists chlorine and salt-water corrosion, which is why it is the standard exchanger material for pool duty.
What warranty does the Varm Silent Pool Series carry?
Solimpeks backs the Varm Silent Pool Series with a 2-year product warranty, stated on this product page.
